The present invention relates to containers'or receptacles for holdingdessicated meats of various kinds during the cooking operation ormoulding after processing.

The shortage of metals prohibits the manufacture of sheet metalcontainers for this purpose and the principal objects of the presentinvention is to provide a carton or cardboard holder for effectivelyholding meats and retaining their Juices and other qualities whilesubjected to the heat of cooking and which will effectively 'withstandthe temperatures to which such goods are subjected. .l

The principal features of the invention consist in providing a foldedsheet of'surfaced card which will form a seamless container presentingsmooth interior faces which will enable the ready removal of thefinished cooked product, and further providing an outer casing forholding the folded seamless sheet'in the required position to receiveand hold the raw materials of the meat loaf or processed meat and whichwill present a strong and effective enclosure for said folded cartonwhich will effectively resistthe heat of the oven.

In the accompanying drawing Figure 1 is a perspective view of myimproved carton shown enclosed within its outer casing and ready toreceive the material to be cooked therein.

Figure 2 is a perspective viewon a reduced scale of the outer enclosurefor the seamless inner carton showing said enclosure in the act of beingfolded. I

Figure 3 is a perspective view 'of the inner seamless meat-holdingcarton on a reduced scale correspondin'g with Figure 2.

Figure 4 is a reduced scale plan of thecardboard sheet prepared forforming the outer enclosure of the meat-holding seamless; rton.

Figure 5 is a plan detail of the single unbroken sheet of material whichis folded shown in Figure 3.

It is well understood by those conversant with the preparation of cookedmeats that deep rectangular metal pans formed of sheet metal have beencommonly used for the cooking of various kinds of meat loaves, and whilesuch practice was common it nevertheless was true that very much panstock was tied up in retail establishments by the dealer desiring tostore thecooked meat loaf untilbrought out for sale in the originalcontainer in which it was cooked. This practice has many advantages forthe into the form retailer but it requires the manufacturer tq haye anextraordinary stock of metal pans.

The present invention has been devised brithe continuedv manufacture.

In carryingthis invention into efl'ect-it ispreferred that aninnerycarton A be provided, which maybe made of a high grade smoothsurfacedcalendered cardboard which willbe highly resistant to absorptionoffats and meat juices.

Such a carton is constructed of a single sheet of cardboard, asillustrated particularly-in- Figure '5. The sheet is formed'with acentral-rectangular portion I surrounded by creases atthe sides and endsrespectively, dividing same from the longitudinal side panels'I-I andthe and panels 3-3.

These side and end panels are -joined by vshaped corner panels 4 and theboundary lines betweenthe panel's 2 "and l and land [are formed bycreases I and I which flare outwardly from the centre panel I.

The corner panels I are formed with creases I centrally of their. widthextending inwardly to the apex of ,the creases j. and I. and at-aztheouter end ofthe-creases I the said corners. 4 are formed with'V-shapednotches'l.

The creased Y-shaped corner members are adapted to be foldedoutwardly..while the panels 2 and! are folded upwardly and inwardly. The

corner folds thus extend outwardly and they are preferably foldedoutside of the endpanels 3, as illustrated in Figure 3. I

A carton is thus provided which is seamless and the flaring end members!when folded-up fit snugly between the inner surfaces of the side members2. A smooth interior is. thus provided in the carton which flaresslightly upwardly sideways and endways. This upward and outwardflarefacilitates the packing of the dessic'ated meat and other ingredientsinto the carton, and w it also provides a tapered clearanceto'enabl'e'the cooked loaf to be easily and therefrom. In order toretain the seamless carton described in a securely folded condition Iprovide quickly removes an outside carton B. This outside cartmispreferably formed from a single sheet of card- 'a,sss,so1 Yuratedbutitwillnottransmittheiuicestoany board. preferably of a muchheavier type and much more open textured than the hard calenderedsurfaced inner carton. This outer carton B h formed with a centralrectangular portion II which is of slightly greater dimensions than thecentral panelvl of the carton A and-extend-- ing along either side andmarked by'longitudinal score lines are the'side panels II, while at theends are end panels is spaced by end score lines.

The end panels it have extending from either side thereof the wingmembers It separated from the panels I! by the slits II and defined fromthe panels it by the score marks is which fiare slightly outwardly fromthe comers of the centre panel Ii.

The ends of the panels I! defined by the slits ll fiare outwardly andattached along the longitudinal outer edges by the doubled score lines Hare longitudinal panels-ll. Thesepreferably have inwardly convergent endscore lines is which define the outwardly extending end tabs II. v

In folding up this outer carton thetabs it are nrst turned upwardlybending on the divergent score lines it. Then the end panels it are bentupwardly, thus bringing the end tabs II inwardly. I'he side panels I!are then bent upwardly, the tabs II being first bent upwardly on theirscore lines, and the panels is are then obstructed inner surfaces andturned over inwardly over the top edges of the tabs ll of the end panelswith the end tabs ll folding against the inner faces of the end panelsII: The folding of these members is clearly illustratedinl 'igurez.

When the panels I. have been folded in to a '7 vertical position ontheinside oi' the tabs It the outside panels lie parallel with thepanels II and the end edges of the tabs 2. meet at the ends of thecarton and thus form an interlock which holds the carton in a solidfolded structiu'e without the necessity of any form of fastening means.

The cartonaisthenplacedinside orthe cartonBandthetop edges ofthe cartonBarecovered by narrow fold strips It and 22 on the side and. end panelsrespectively of the carton A.

. A double. carton when thus assembled forms a very strong and compact.holder, presenting a smooth inner surface into which the meats and otheringredients to make up a meat ice! are placed either raw orpre-processed.

The packed carton may be placed in an oven-andbakedintheusualmanneranditisfound that the hard and calenderedsurfacedcardboard of the inner carton eifectively resists the passage ofthe meat Juices and greases there- Thisinnercartonmaybecomesatandinterlock when folded against the 'tinued in production even thoughmaterial extent.

What I claim as my invention is: 1. A meat-cooking carton comprising ancarton of hard calendered card having thetom,sideandendwallspresentingsmuzofli having a bottom andwith'saidendwalls tie s5 Bis ing formed of a dark heat-absorbingcardboard.
